Abstract

Introduction: Street food vendors play a significant role in providing ready-to-eat food in urban areas, including East Surabaya, which has hundreds of street food outlets. However, issues related to hygiene and sanitation practices among food vendors remain a significant challenge. This study aimed to examine the factors influencing the knowledge and hygiene practices of food handlers among street vendors in East Surabaya.Methods: This observational study used a cross-sectional approach and included 86 food handlers. Samples were selected using a purposive sampling technique with predetermined inclusion (location, age, willingness, and work period) and exclusion criteria (not active, health condition). Data were collected using a structured questionnaires. The independent variables were age, gender, and education, and the dependent variables were knowledge and behavior. Statistical analysis was performed using the chi-square test, and the Spearman test was used for ordinal data analysis.Results: The results showed that 68.6% of respondents exhibited inadequate hygiene behavior, a proportion that was particularly prominent among those aged ≤ 30 years (77.8%), males (83.3%), and high school graduates (79.3%). Respondents' knowledge varied by age, gender, and education. Strong knowledge was more prevalent among female respondents and those with higher levels of education. Significant relationships were identified between sex and education level with knowledge (p = 0.000 and p = 0.005), as well as between sex and hygiene behavior (p = 0.002).Conclusion: Female gender was the determinant for better knowledge and hygiene behavior, while higher education was the determinant of knowledge of food handlers. This indicates the need for more targeted educational interventions to improve hygiene practices among informal food handlers.

Abstract

Background: Oxidative stress can cause health problems for workers and affect productivity for workers. Low-Density Lipoprotein (LDL) and Malondialdehyde (MDA) levels a biomarkers for systemic oxidative stress. Car painting and body repair businesses play a crucial role in preventing corrosion and damage from crashes by employing a variety of processes. The worker in the stage poses the highest risk of exposure to the chemical substance known as toluene. Objective: The purpose of this study is to investigate the relationship of toluene intake with Low-Density Lipoprotein (LDL) and Malondialdehyde (MDA) levels. Methods: This study employed an observational research design with a cross-sectional method. All 30 car painting workshop workers in sanding, caulking, painting, polishing, and finishing are included in this research. Workers were measured for exposure to Toluene and Low-Density Lipoprotein (LDL) and Malondialdehyde (MDA) levels. Data were analyzed descriptively and statistically. Results: Almost half of the total workers are adults. More than half of the total workers have a working period of 8 hours/day, have a working period of up to 10 years, and BMI in the normal category. Only a small number of workers do not smoke. Toluene exposure that enters the body of workers has more than the reference dose and is found in more than half of the total workers. Most workers have optimal LDL. More than half of the total workers have low MDA. The results of the Toluene exposure test with LDL obtained p = 0.098, and toluene exposure with MDA (malondialdehyde) obtained p = 0.045. Conclusion: There is a relationship between Toluene and MDA, but not with LDL. This indicates the need for efforts to anticipate Toluene exposure in companies to prevent oxidative stress, preceded by an increase in MDA.
